SPECIFICATION forming part of Letters Patent No. 637,734, dated November21, 1899.

Application filed February 4, 1899. Serial No. 704,569. (No model.)

To aZZ whom it may concern:

Be it known that I, JULIUS O. HALL, a citizen of the United States,residing at Wallingford, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inMincing-Machines and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention has for its object the provision of a mincing-machine ofthe rotary type and embodying a force-feeder, cutters, and actuatingmechanism therefor which will be capable of being quickly taken apartfor cleaning, sharpening, or adjusting of the cutters or for any desiredpurpose and which will admit of the separated parts being easilyassembled without'the use of tools.

A further purpose of the invention is to dispose the parts so thatjuices expressed from the substance being com minuted will not escape atanypoint other than the common discharge, from which they will escapeinto the vessel or receptacle arranged for therecep tion of the mincedsubstance.

The invention furthermore has for its object to so mount theforce-feeder and cutting mechanism that the latter may be adjusted fromwithout the body and while the machine is in operation, also to improvethe general construction of the machine, whereby its capabilities foreffective service are increased.

The invention is set forth in detail in the novel features andcombinations of parts, as more particularly recited in the appendedclaims.

In the drawings, Figure 1 is a perspective View of a rotarymincing-maohine constructed in accordance and embodying the vitalfeatures of the invention. Fig. 2 is a vertical central section of thebody, hopper, and forcefeeder, the driving mechanism and clamp beingshown in full. Fig. 3 is a top plan view of the frame, the force-feederbeing removed. Fig. 4 is a perspective view of the forcefeeder invertedand having thecutting mechanism in position. Fig. 5 is a detail view ofthe lower end portion of the force-feeder inverted,

the cutting mechanism being removed. Fig. 6 isa detail view of afour-armed cutter which is designed to take the place of the two-armedcutter when the mincing is required to be liner. Fig. 7 is a detailperspective view similar to Fig. 5, showing the cutter adjacent to theshouldered end of the feeder in position.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The frame of the machine consists of the vertically -arrangedcylindrical body 1, the hopper 2 springing from the side of the body 1and comm unicating therewith,a down wardlyextending arm 3, providedat-its lower end with a clamp 4 of ordinary construction for attachmentof the machine to a table-ledge or like support, and a fixed bridgetree5 for supporting the force-feeder and the parts attached thereto. Ajournal 6 projects laterally from a side of the hopper and supports thegear-wheel 7,to which the operating-crank 8 is applied. A hopper2 flarestoward its upper end, so as to receive the substance to be comminuted,and its lower outer portion curves downwardly and inwardly toward thebody 1, so as to direct the substance therein and obviate the formationof any projecting part for the lodgment of the substance in its passageto the cutting mechanism. A series of ribs 9 are provided upon the innerside of the lower portion of the hopper and are obliquely arranged andserve to prevent the moving of the substance by the force-feeder to oneside of the hopper.

A spindle 10 is secured at its lower end centrally of the bridge-tree 5and rises vertically therefrom and receives the force-feeder 11. Theupper end portion ofthe spindle is threaded for a short distance, asshown at 12, and

receives a tension-nut 13 for the purpose presently to be described. Aportion of the spindle adjacent to the threaded terminal 12 is madesquare and receives a washer, which is prevented from turning upon thespindle by closes the'upper end of the body 1, and with a verticalextension 16, to which is secured the gear-wheel 17, which is in meshwith the tate therewith in the operation of the ma;

chine. A disk. or plate 19 is mounted upon the extension 18 betweenupperand lower cut-' ters 20 of like formation, and this disk isperforated to provide escape-openings for the substance during themincing action of the machine. This plate or disk 19 actsconjoin-tlywith the cutters 20 to comminute the substance passingthrough the machine. The plate 19 is fixed and is prevented from turningin any desired manner, and, as shown, it

is formed with outwardly extending lugs 21,

which enter vertical grooves 22, formed in the inner walls-of thebody 1. The lower end of the feeder is formed at opposite points withshoulders 23, against which the arms of the uppermost cutter obtain abearing, thereby preventing the turning of said cutter upon theextension 18. These shoulders are terminals of the spiral ribs, whichproject beyond the end of the feeder. The parts 19 and 20 are retainedupon the extension 18 by means of the nut 24, fitted to the lowerthreaded end of said extension. The not 24: is ofcircular form andenters a recess 25, formed in the upper side of the bridge-tree 5.

The cutters 20 are of like formation and embody two arms, which areoppositely disposed, and the coarseness of the substance when out willdepend upon the relation of the cutters 20. When said cutters 20 arearranged in parallel relation, the substance will becut into coarseparticles, and by arranging the cutters right-angularly or in crossingrelation the particles will be smaller in size. If it be required to cutthe substance into still smaller particles, the lowermost two-armedcutter is replaced by the four-armed cutter shown in Fig. 6. 1

When the force-feeder is placed upon the spindle 10, the cutters and theperforated disk or plate 19 may be held in close relation by turning upthe tension-nut 13. This element .13 also serves to hold the feederwithin the body 1, and when removed said feedercan be lifted from thebody for/cleaning or any purpose. The construction is of such characteras to preclude the escape of juices from the .body 1 except by way ofthe lower end, which .is open and forms a common discharge for allmatter fed to the machine through the hopper 2.

The machine is particularly adapted for lnincing meat, but may be usedfor cutting up fruits and vegetables, and in adapting the invention forany particular or special use it is to be understood that variouschanges in the form, proportion, and minor details may be resorted towithout departing from the spirit ofthe invention. 7 p g Having thusdescribed the invention, what is claimed as new isr 1. In a machine ofthe character described, thecombination of a vertically-arranged body Iopen at its upper end for the introduction of the feeder and cutterandprovided at one side with a hopper and having a bridge-tree at itslower end, a non-rotatable or fixed spindle rising centrally from thebridge-tree and rigidly attached thereto at its lower end, aforce-feeder mounted loosely upon the fixed spindle and havingindependent and free rotation thereon and provided with cuttingmechanism, means appliedto the upper end of the spindle for securingthe'force-feeder thereon and holding itwithin the body of the machine,and actuating mechanism for rotating the feeder abo ut the spindle,substantially .as set forth.

2. In a mincing-machine of the nature specified, the combination with avertically-disposed body open at its upper end for the introduction ofthe feeder and cutter and havinga hopper at one side and provided at itslower. end with a bridge-tree, and a non-rotatableor fixed spindlerigidly attached at its lowerend to said bridge-tree and passingupwardly through the body of the machine, of a force-feeder mountedloosely upon the bedspindle' and having independent and free rotationthereon, and having a-pendent extension at its lower end, cuttingmechanism mounted upon said pendent extension, means applied to theupper end of the spindle for holding the force-feeder thereon and withinthe body of the machine and at the same time serving to maintain theelements of the cutting mechanism in intimate or working relation, andactuating mechanism for rotating the feeder-about the spindle,substantially as set forth. p

3. Ina mincing-machine of the variety set forth, the combination with avertically-arranged body open at its upper end and having a hopper atone side and provided at its lower end with a bridge-tree, and anon-rotatable or fixed spindle rigidly attached at its lower end to thebridge-tree and passing upwardly through the said body, of a force-,

the upper end of the fixed spindle for holding the feeder thereon andwithin the body of the machine and the'elements of the cuttingmechanismin working relation, substantially as described. I

4:. In combination, a vertically-arranged body open at itsupper end andhaving a hopper at one side and formed with inner vertical grooves, afeeder insertible through the upper open end of the said body and havinga pendent extension at its lower end, a perforated plate or disk looselymounted upon said extension and having outwardly-extending lugs to movein and interlock with the grooves of the aforesaid body to preventrelative turning of the plate, cutters placed upon the said pendentextension upon opposite sides of the perforated plate and rotatable withthe feeder, means applied to the lower end of the pendent extension tosecure the perforated plate and cutters thereon, and independent meansfor holding the feeder within the body and clamping the elements of thecutting mechanism upon the extension thereof, as and for the purposespecified.

atboth ends and having a hopper at one side, alaterally-extendingjournal and a clamp and bridge-tree at its lower end, a spindle rigidlyattached at its lower end to the bridge-tree and having its upper endthreaded, a forcefeeder mounted to turn freely upon the fixed spindleand having upper and lower extensions and a head to close the upper endof the body, upper and lower cutters mounted upon the lower extension ofthe feeder and rotatable therewith, a perforated plate placed upon saidlower extension between the cutters and interlocking with the body,means for securing the cutters and plate upon the said lower extension,a gear-wheel slipped upon the upper extension, a clamp-nut applied tothe upper end of the fixed spindle and holding the feeder within thebody, the gear-wheel upon the feeder and the cutters and perforatedplate in working relation, and a companion gear-wheel mounted upon thesaid lateral journal and meshing with the aforesaid gear- Wheel andprovided with an operating-crank, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
